Erno "Emppu" Matti Juhani Vuorinen was born on the 24th of June in Kerava, Finland. He started to play guitar at the age of 12 as a private study. Emppu is often referred to as "The short one" when amongst Nightwish members, as well at his other projects, standing at only 5'5" (165cm) in height. Emppu most often supports the keyboard or orchestral parts of Nightwish songs, Marco Hietala easing back to allow the higher pitched guitar of Emppu to take precedence. Emppu's solo techniques include short range tapping and minor to extreme, whammy bar use for vibrato.
